GEOLOGY

Detailed explanation-1: -Polarized light microscopy is capable of providing information on absorption color and optical path boundaries between minerals of differing refractive indices, in a manner similar to brightfield illumination, but the technique can also distinguish between isotropic and anisotropic substances.

Detailed explanation-2: -The polarizing microscope is particularly useful in the study of birefringent materials such as crystals and strained non-crystalline substances. It is widely used for chemical microscopy and optical mineralogy. The current specimen is equipped with a quick change, centering nosepiece and a graduated, rotating stage.

Detailed explanation-3: -Polarized light microscopy uses polarized light that travels through a double refracting material, then generated into a high-contrast image via the collection of light by a second polarizing filter.

Detailed explanation-4: -A regular light microscope uses unpolarised white light. This is the type of light that we see, and its waves vibrate in random directions. Polarised light, however, has waves that vibrate only in one direction, and cannot be seen by us normally.
